TO ALL WHOM IT MAY OQNGERN: h Be it known that I, CHARLES E'. ABBOTT, of Maiden, in the county of Middles e x, and State of Massachusetts have invented certain Improvements in Extinguishers for Lamps, of which the following is a fnll, clear, and exact description, reference being had to the accompanying drawings,'making part of this specification, in Whichj Figure l is'a vertical sectionthrongh a wick-tube, with my improved extinguisher applied thereto, the wick being raised into the position it occupies when lighted.

Figure is a vertical section through the'same, the wick being lowered, and the extinguisher closed over itstop. I

f :AFignre iii; a perspective view-ot my extinguisher applied to a wick-tube.

My invention has for its object to provide a simple and ready means of extinguishing the flame of lamps,

without creating the smokeand disagreeable odor which attend the ordinary method of extinguishing the flame; and my invention consists in a wick-tube, so'formed that theupper portion of ope of its sidcs will close over the wick as soon as it is lowered below the top of the tube. I

To enable others skilled in the' art to understand and use rnyinvention, I will proceed to describe the manner in which I have carried it out.

.In the said drawings, A represents the upper part of -a burner of, an ordinary kerosene-lamp, through which passes the tube B, for the reception of the wick C, which is'raised and lowered, as requiredpby a toothed wheel, D, in a well known manner. 7

One side of,the wick-tube is made in two pieces, a b," the upper portion'or lid, 21, being hinged or pivoted at c to the lower or main portion, 6, which 'is provided with. a stop, d, against which the upper portion, a, is pressed and retained by thewick when raised in a position to be lighted, (see fig. 1.) Immediately on lowering the wick, the upper portionor lidbeing inclined inward, and'havingnothing to support it, drops over byits gravity, and encloses the top ofthe wick, thereby extinguishing the'light, and preventing the smoke and unpleasant odor from arising, and also preventing the evaporation of the oil.

I prefer to make the lid a thicker at its top than at its bottom, which is rounded off to a point, as seen in figs. 1 and 2, as by this construction thetop of-the lid will be heavier, and will therefore more rapidly fall for wardover the top of the wick; and this result is rendered more certain from the fact that the hinge or point at which itis-pivoted is placed entirely on the outer surfajce of the tube.

In order to still further assist the fall of. the lid, as required, the step 11, instead of being made rigid, may he made flexible, and serve as a spring, without departing from the spirit of my invention.

z Claim, I What I claim as my invention, and desire to secure by Letters Patent, is The lida, so hinged and supported that when the wick C is lowered, the lid will fall over it and close the mouth of the'wick-tube B, substantially as set forth.

CHARLES E. ABBOTT.
